' ting to strain the rosin.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed February 1. i907. Serial No. 355.330.

' batting upon a wire sieve at the bottom of the strainer box and topour the melted rosin upon the cotton bat- Experience has shown that inthis process much of the rosin passes through the sieve between thecotton batting and the sides of the box without having first beenfiltered through the cotton, and the object of the present" invention isto provide means for preventing this undesirable leakage.

A further object of theinvention is to generally improve this class ofdevices so as to increase their utility, durability and efficiency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may beresortcd to within the scope of theappended claims.

In the accompanying drawings forming a part oi this specification:Figure 1 is a longitudinal sectional view of a strainer donstructcd inaccordance with my invention showing the same in position to receive therosin from the trough. Fig. 2 is a transverse sectional view of thesame. Fig. 3 is a front elevation of the trough. Fig. 4 is a sideelevation of the trough.

Similar numerals. of reference indicate corresponding parts in all ofthe figures of the drawings.

The improved device consists of a plurality of telescopic open endedreceptacles or boxes 5, 6 and 7, said boxes being preferably elongatedin shape and having their side walls tapered or inclined towards thereceiving Vessel 8.

The receptacle 7 is provided with opposite disposed spaeed handles 9which rest on the upper edge oi the containing vessel 8; there beingsimilar handles 10 formed on the receptacle (5 and bearing against theupper edge of the lower receptacle 7 as shown.

The upper receptacle 5 is approximately one-half the length of the lowerreceptacle and constitutes a means for catching and retaining the rosinchips from the trough or spout 11, the latter leading from a still ofany suitable construction.

Secured to the bottom of each of the boxes 6 and 7 is a strip ofwire-netting or similar material 12, the latter being retained in placeby longitudinal and transverse retaining strips 13 and 14 which may benailed or otherwise rigidly secured to thelower edge of each receptacle,there being intermediate supporting or reinforcing strips 15 extendingtransversely across the bottom-of each receptacle andv disposed incontact with the wirenetting, as best illustrated in Fig. 1 of thedrawing.

interposed between the wire-netting and the lower edge of each sieve boxis a marginal impe'riorate strip 16 which projects inwardly above thescreen and forms a partial closure for the bottom of the box and alsoserves to support the cotton batting 17 and prevent the rosin fromleaking between the cotton and the sides of the box. I

When the cotton batting is placed in the strainer it is lapped over thesides and ends of the marginal impenforatc strip 16 and any leakagebetween the cotton and edges of the box is thus effectually prevented.

The trough 11 preferably consists oi. a substantially cylindrical shapedrun-way having its longitudinal edges spaced apart and connected by oneor more transverse strips 18, said trough being relatively rleep so asto prevent any leakage over the upper edges of the trough withconsequent waste of the rosin and danger of burning the operator.

In straining the rosin the latter is iirst run through the chip catcher5 into the top strainer 6 and allowed to settle for about live minutesor until the heavier sediment and dirt is deposited on the cottonbatting 1.7. A hole is then punctured in the cotton batting thusallowing the rosin or lighter material to flow through said opening intothe second strainer, leaving the waste or foreign matter adhering to thecotton batting in the top strainer. The rosin being relieved of a largeproportion oi dirt and sediment percolates through the cotton batting inthe second strainer into the containing vessel 8 thus rendering the sameclear and free from all impurities.

The several boxes or receptacles may be made in any desired shape orsize and as many of said sieve boxes may be employed as is founddesirable to effectually strain or filter the resin.

Having thus described the invention what is claimed is: g

A strainer consisting of an open ended receptacle having converging sideand end walls and provided with oppositely disposed handles extendinglaterally from said end walls, a strip of wire netting covering thebottom of the receptacle, iongirudinai and transverse reinforcing stripssecured to the lower edges of the receptacle and V eeegss hem-i againstthe wire netting, a marginal imperfornte I against. the lnterlur Wallsof the receptacle at the nmrglnal strip i nnscil between the wirenetting and lower eclgvs strip.
